This tab includes preferences that affect the colors of the wires during simulations as well as the colors used for Karnaugh diagrams

In the upper part, the colors of the wires in the different situations of the simulation are defined, as well as the characters that will be used in the display of the state of the lines.

In the lower part, these are the colors used to represent the groups in the Karnaught diagrams.

The use is simple, Click on the buttons and a color selector appears. You can then make your choice and change the color.

Two buttons are present, Default colors to return to the default colors and Colorblind colors for a setting facilitating the reading of people with difficulties with color perception.
